SPECIFICATION forming part of Letters Patent No. 632,375, dated September 5, 1899.

Application filed May 18, 1899. Serial No. 717,351. (NIJ model.)

'o all whom, it may con/cern.-

Be it known that I, DAVID SINCOCK, a resident of Clyde Park, in the county of Park and State of Montana, have invented certain new and useful Improvements in Mowing Ma'- chines and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in mowing-machines, the object of the invention being to provide a mowing-machine with imi proved cutter-bar-operating means.

A further object is to provide improved means on the cutter-bar of a mowing-machine for reciprocating the cutter-bar.

A further object is to so construct the cutter-operating mechanism of a mowing-machine that the cutter-bar and finger-bar can be raised or lowered Without affecting the operating mechanism in the slightest.

A further object is to so construct a mowing-machine that the cutter-operating mechanism can be readily disconnected from the cutter-bar to permit the easy removal of the latter.

A further object is to provide a mowingmachine which will be extremely simple in construction, cheap to manufacture, and most effectual when in operation.

Vith these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view illustrating my improvements. Fig. 2 is a View in section of same, and Figs. 3, 4, and 5 are views of details.

A represents the frame of my improved mowing-machine, supported by the axle 1, which is carried by the Wheels 2, as shown. A tongue 3 is secured to the frame A and is adapted to support any approved drivers seat. (Not shown.)

The frame A is provided with a bracket 4, projecting to one side of the machine and adapted to support a horizontally-disposed shaft 5, mounted in suitable bearings in the secured in lugs 18 on a shoe 19.

loosely-mounted frame 21.

bracket and projecting through one side therelof for a purpose more fully hereinafter exversely-disposed connecting strips or plates The rear ends of the longitudinally-disposed strips 15 project beyond the rear transverse strip 16 and are provided with holes or openings for the reception of a rod or bolt 17, The shoe 19 is provided at points between its ends with lugs 20, to which are pivotally secured 'a The front member 22 of the frame 21 connects the front lug 2O on the shoe with a lug or projection 23 on the bracket 4, and a coupling-yoke 24 connects the member 22 with the main portion of the frame, which latter is pivotally connected to downwardly-projecting lugs 25 on the frame A, as shown. The frames A and 2l and bracket4 are held out of contact with the ground (when the tongue 3 is raised) by means of a strip or brace 26, secured at its ends, respectively, to the tongue and frame A. A'inger-bar 27, having a series of split fingers 28 on its front edge, is secured to the shoe 19 and provided at its outer end with any approved track-clearer 29.

My improved cutter-bar 30 is mounted on the finger-bar 27 and held against rearward movement by means of lugs or projections 31, secured at points throughout the length of the finger-bar and adapted to overlap the cutterbar when in place. The cutter-bar is provided at its inner end, on its upper face, with enlargements or blocks 32, spaced apart and provided with inclined inner ends to form an approximately V-shaped recess 33. The shoe 19 is made with a groove 34 for the reception of the contracted inner end of the cutter-bar to permit the cutter-bar between the ends of the blocks 32 to lie ush with the upper face of the shoe, and the frame 13 is provided at diametrically opposite points with recesses 35 for the free passage of the blocks 32.

A wheel 3G is mounted in the frame 13 and secured on the shaft 12 and provided around its periphery with a cam flange or web 37, comprising a series of diagonally-disposed sections connected together at their ends to form a cam-flange on the periphery of the wheel. This flange or web 37 is disposed in the recess 33 between the blocks 32 and as the wheel revolves engages first one block 32 and then the other, thus carrying the cutterbar from one extreme to the other and reciprocating the same.

The frame 13 is provided on its forward transverse strip with parallel lugs 38, between which the forward lug 2O on the shoe 19 is disposed, and a catch 39 is pivotally mounted on the forward lug 20 and adapted to be turned to lock the frame 13 in its downward position on the shoe. Any ordinary lifting-lever (not shown) may be employed for raising and lowering the finger-bar and cutter-bar.

The operation of my improved device is as follows: Motion is transmitted from the sprocket-wheel 7 to the sprocket-wheel 6 by the sprocket-chain 8 to revolve the sleeve 9,

-rod 11, and shaft 12, carrying the operatingwheel 36,which latter,as heretofore explained, operates to reciprocate the cutter. It will be seen that as my improved operating-wheel 36 is' mounted directly on the finger-bar, or shoe forming a part thereof, and connected with the operating mechanism by a telescoping flexible shaft, the nger-bar can be raised or lowered without aecting the operating of the device in the slightest, as the telescopic sections of the iiexible shaft will take up the shortening of the shaft and revolve the operating-wheel at precisely the same speed to give the cutter-bar its proper throw and f always end the throw of the knives in the center of the split ngers.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my in vention, what I claim as new, and desire to secure by Letters Patent, is-

1. Ina mowing-machine, the combination with a frame, of a finger-bar pivotally connected therewith, a cutter-bar inovably mounted on the finger-bar, a frame pivotally connected with the nger-bar and disposed thereon', a wheel revolubly mounted in the frame and a cam-iiange on the periphery of said wheel adapted to engage and reciprocate the cutterbar.

2. In a mowing-machine, the combination with a frame, a finger-bar pivotally connected therewith, and a cutter-bar movably mounted on the finger-bar, of a wheel mounted on the finger-bar, a cam-flange on said wheel adapted to reciprocate the cutter-bar, operating mechanism for the cutter-bar and a flexible telescopic shaft connecting said operating mechanism with the wheel on the finger-bar.

3. In a mowing-machine, the combination with a frame, of a finger-bar pivotally connected with the frame, a shoe secured to the finger-bar, a frame hinged tothe shoe, means on the shoe for locking the frame in position, a cutter-bar having one end disposed in said frame, a wheel revolubly mounted in the frame, shoulders on the cutter-bar, a camiiange on the wheel for engagement with the shoulders on the cutter-bar to reciprocate the latter and a flexible shaft connecting said wheel with the operating mechanism for the mowing-machine.

4:. The'combination in a mowing-machine of a frame, a shoe hinged thereto, a finger-bar secured to the shoe, a cutter-bar, beveled shoulders on said cutter-bar, a wheel mount'- ed on the hinged shoe over the cutter-bar and provided with a cam-fiange operating between said beveled shoulders and means for rotating the wheel.

5. In a mowing-machine, the combination with a frame, of a shoe having a hinged connection in line with its longitudinal axis, with said frame, a finger-bar secured to said shoe,

a cutter-bar mounted on the finger-bar and4 adapted to project across said shoe, beveled shoulders on said cutter-bar, a frame mounted on the shoe and bridging the finger and cutter bars, a cam-wheel mounted in said frame and adapted to engage said beveled shoulders on the cutter-bar to reciprocate the latter and means for rotating said cam-wheel.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

DAVID SINCOCK.
